Answer: B = 70°, b = 29.2; c = 29.2

Step-by-step explanation:

sum of angles in a triangle is 180

40+70 +X = 180

X is the last angle

110+x=180

x= 180-110 =70

A= 40°

B= 70°

C= 70°

the triangle is Isosceles triangle meaning two sides are equal , angle B = angle C

Answer:

  256,096 ft²

Step-by-step explanation:

<u>Pyramid Area</u>

Each of the four faces is a triangle with a base of 756 feet and a height of 612 feet. The area of that triangle is ...

  A = 1/2bh

  A = 1/2(756 ft)(612 ft) = 231,336 ft²

The total area of the four visible faces of the Great Pyramid is ...

  pyramid area = 4 × 231,336 ft² = 925,344 ft²

__

<u>WTC Area</u>

Each of the four rectangular side faces of the WTC tower has a base length of 208 ft and a height of 1368 ft. The area of it is ...

  A = LW = (208 ft)(1368 ft) = 284,544 ft²

The area of the square top of the tower has an area that is ...

  A = s² = (208 ft)² = 43,264 ft²

The total area of the four visible sides and the top is ...

  WTC tower area = 4 × 284,544 ft² +43,264 ft² = 1,181,440 ft²

__

The difference between the areas is ...

  WTC tower area - Great Pyramid area =

     1,181,440 ft² -925,344 ft² = 256,096 ft²

The difference in visible area is 256,096 ft².
